Abstract
1330818 Detecting gas or dust DRAGERWERK A G 30 Aug 1972 [30 Aug 1971] 40269/72 Headings G1B and G1X A predetermined volume of gas or gas plus dust is drawn through a measuring or detecting means 8 by the movement of a bellows 2 within a container 1. A valve 13 connects the container 1 alternately to a suction pump 15 and via tube 16 to the atmosphere. During pumping, the bellows 2 expands until a wall 17 abuts an adjustable stop 21, gas being drawn through the means 8 until the pressure within the bellows 2 is atmospheric. A pressure detector 10 then actuates the valve 13 to disconnect the pump 15 and open the container 1 to the atmosphere thereby allowing a biasing spring to expel the gas from the bellows 2 via valve 20. When a switch 19 is actuated by abutment 18, the pump 15 is reconnected to the container 1 so as to initiate another cycle. In a modification the spring 5 is within the bellows 2 a pressure pump then being used to deflate the bellows Fig.2 (not shown). In a further modification, a suction pump 15 is used to deflate the bellows 2, the spring 5 being within the bellows 2 to expand it on termination of pumping Fig. 3 (not shown).
